When PickContactAsync() returns, it prevents other windows to show

[borrmann]

Description

I pick a contact. If there is more than one phone number, I want to ask the user which number he wants to pick. When I open a new DisplayActionSheet, it doesn't open. I tried to use the49 BottomSheet instead, which does open for a moment, but is then dismissed.

var contact = await Microsoft.Maui.ApplicationModel.Communication.Contacts.Default.PickContactAsync();
var phones = contact.Phones.Select(x => x.PhoneNumber).ToList();
string res = await Application.Current.MainPage.DisplayActionSheet("chosse a number", "cancel", null, [.. phones]);

Steps to Reproduce

1. Pick a contact
2. Show a DisplayActionSheet or another window
3. The DisplayActionSheet does not show

Version with bug

8.0.3

Is this a regression from previous behavior?

Yes, this used to work in .NET MAUI

Last version that worked well

7.0.49

Affected platforms

iOS

Affected platform versions

iOS 17, not sure about other

Did you find any workaround?

before opening another window, add a delay of 1000ms. Strangely, 500ms is not enough. await Task.Delay(1000); string res = await Application.Current.MainPage.DisplayActionSheet("chosse a number", "cancel", null, [.. phones]);

Relevant log output

This issue has been verified using Visual Studio 17.12.0 Preview 1.0(8.0.80 & 8.0.3), Can repro it. and works fine on 17.11.1 (7.0.49). It is a regression from .NET 7 to .NET 8. Add workaround as prompted "await Task.Delay(1000);" Can work normally.
